CURTAIN-ROLLER.

Specification of Letters Patent.

Patented Tan. 26, 1909.

Application filed June 8, 1907. Serial No. 377,887;

To all whom it may concern:

Be it known that I, THOMAS DIGNEY, a citizen of the United States, andresident of Bridgeport, in the county of Fairfieldand State ofConnecticut, have invented certain new and useful Improvements inGurtain- Rollers, of which the following is aspeciiication.

This invention has relation to shade rollers, and it consistsin thenovel construction and arrangement ofits parts, as'hereinafter shown anddescribed. The object of the invention is to provide a roller of thecharacter indicated which is especially adapted to be used upon thewindows of carriages and automobiles and so forth. The parts arecompactly arranged, inclosed and occupy but small space and consequentlypresent no obstruction to those entering or leaving the vehicle.

The roller consists primarily of a shaft supported at its ends inbrackets which are attached to the sashing or casing of the window, andthe said roller is held against rota.

tion in the said bracket. A cylinder is closed at its ends by heads, andthe said heads are journaled for rotation upon the shaft. One of thesaid heads is provided with a boss to which one end of a coiled springis attached; the said spring surrounds the shaft and lies entirelywithin the cylinder, and its opposite end is fixed to the shaft. Theopposite end portion of the shaft is provided with a transverse opening,and the other cylinder head is located adjacent the said opening. Thelast said cylinder'head is provided upon its inner side with integralpins upon which are pivotally mounted pawls. The pins and pawls arepreferably three in number. The inner faces of the cylinder heads areprovided with concentric grooves which receive the ends of the cylineder, and the cylinder ends are secured in the said grooves by means ofsolder, thus inclosing all the operative parts of theroller.

The shade is arranged to wind upon the enters the bracket 3.

pins but with the pawls removed. Fig. 4 is a transverse sectional viewof the cylinder out on the line 4 -4 of Fig. l, and showing operativeposition of pawls. Fig. 5 is a perspective view of the head used at theopposite end of the cylinder.

The shade roller comprises the shaft 1, one end of which is screwthreaded into the bracket 2, and the opposite end slidably The saidbrackets 2 and 3 are adapted to be screwed or otherwise secured to thewindow sashing or casing 4. The cylinder head 5 is journaled upon oneend of the shaft 1, and the cylinder head 6 is journaled upon theopposite end thereof. The heads 5 and 6 are provided with concentricgrooves 7, which receive the opposite ends of the cylinder 8. The head 5is provided upon its inner face with a boss 9 to which is attached oneend of the coiled spring 10. The said spring surrounds the shaft 1 andlies wholly Within the cylinder 8, and its opposite end is attached tothe shaft 1 at the point 11. The head 6 is provided upon its inner facewith the integral pins 12 preferably three in number. The pawls 13 arepivotally mounted upon the said integral pins, and the inner ends of thesaid pins are slightly flattened or riveted for the purpose of retainingthe said pawls thereon. This integral construction of pins obviouslyavoids the necessity of drilling the said head and providing specialpins which have to be placed and secured therein. Surrounding the baseof each integral pin I provide a slightly raised milled bearing '12which holds the parts off from the head and insures their freeoperation. The shaft 1 is provided in the vicinity of the head 6 with atransverselydisposed perforation 14 which is ada ted to receive the endof any one of the paw s 13 in the usual manner. The shade 15 is attachedto the periphery of the cylinder 8 and is adapted to wind thereon andunwind therefrom.

From the foregoing description it is obvious that'a shade rollerspecially adapted for the purpose set forth is provided that the partsare compactly arranged and offerno obstruction, and that the arrangementis of a simple and durable nature. The shade is manipulated by drawingthe same so that the cylinder 8 rotates in one direction and increasesthe tension of the spring 10 when the said shade is released and thetension of the said spring comes into play, so that the cylinder 8 isrotated at such a rapid rate of speed as to swing the ends of the parade13 centrifugally against the inner side of the said cylinder and awayfrom the perforation 14 in the shaft 1. At the same time the shade 15 isWound upon the said cylinder. WVhen the shade is completely Wound uponthe cylinder or the rotation of the cylinder 8 is checked, the end ofone of the pawls 13 Will fall in the perforation 14: and retain thecylinder 8 against further rotation.

What I claim is 1-. A shade roller comprising a stationary shaft uponWhich is journaled a revolving member, a flat portion adjacent one endof said shaft having a slot extending therethrough, paWls for engagingsaid slot mounted on said revolving member, screw threads on one end ofsaid shaft adapted to screw into a bracket and a reduced cylindricalp0rtion 011 the other end to permit of longitudinal adjustment, saidslot of a length suiiicient to permit of shifting of said pawls duringsuch adjustment.

2. As a new article of manufacture, a disk head for the revolvingcylinder of a curtain roller, an annular groove on the inner surface ofsaid head for the reception of said cylinderpintegral pins within saidgroove having raised bases, and pawls pivoted on said pins and spacedfrom said. disk face by said bases.
